Probably A/MP in NHRA trim would be a tunnel ram set-up. Caleb's car is a perfect example of an A-B/MP car of the early 70's. Those cars ventured into Pro Stock on some weekend invitational meets at the local dragstrips. Looks like an NHRA SS/D car without the aluminum heads. Can't remember if you could run aluminum heads on a 427 in NHRA SS back then on a camaro.
